http://csharp-video-tutorials.blogspot.com/2015/04/jquery-change-event.html
In this video we will discuss jQuery change event.
change event is fired when an element value changes. All the following elements fire this event
1. input
2. textarea
3. select
select, radio buttons and checkboxes fire the change event as soon as a selection is made, where as the other element types wait until they loose focus.
For the HTML used in the demo, please refer to my blog using the link below
http://csharp-video-tutorials.blogspot.com/2015/04/jquery-change-event.html
As soon as the selection in the dropdownlist changes, we want to handle the change event and display the selected value in the div element with id="divResult". In the example below, we are using the id selector, so only the select element change event is handled.
$(document).ready(function () {
$('#ddlCity').change(function () {
var selectedValue = $(this).val();
if (selectedValue == "Select")
selectedValue = "Please select city";
$('#divResult').html(selectedValue);
});
});
The following code handles the change event of all the input elements (textbox, radio button, checkbox). Notice that in this example we are using the jquery element selector. Change event of select and textarea is not handled.
$(document).ready(function () {
var result = '';
$('input').change(function () {
if (result == '') {
result += $(this).val();
}
else {
result += ', ' + $(this).val();
}
$('#divResult').html(result);
});
});
The following code handles the change event of all the elements on the page. Notice that in this example we are using the jquery class selector.
$(document).ready(function () {
var result = '';
$('.inputRequired').change(function () {
if (result == '') {
result += $(this).val();
}
else {
result += ', ' + $(this).val();
}
$('#divResult').html(result);
});
});

Sometimes we want to required add or remove dynamic html fields in a form. We have already seen how to add or remove simple html input fields dynamically in a form, but how to add or remove dynamic select box into form dynamically. So We have make this simple tutorial to learn how can we add or remove select box data dynamically using Jquery and how can we insert multiple select box data into Mysql table by using Ajax with PHP without refresh of webpage.
For Add or remove drop down list box data dynamically into form, we have developed a jquery script by using script we can add or remove multiple select box fields very easily. In this script also useful for insert multiple values of drop down list box in PHP by using Ajax. In this post we have discuss how to generate dynamic select box HTML fields in a form while filling of form and after adding multiple select box data into the database. For this we have used Jquery to developed this type of functionality with very short, simple and powerful. By using this script we can add or remove dynamic select box fields very easily. After adding multiple select box fields and submit those select box value into PHP script by using Ajax and inserted into Mysql table.
In this post to learn how to add or remove dynamic Select Box data dynamically using Jquery and insert into Mysql table using Ajax with PHP. So Here we have make simple invoice script for add multiple item data into single order. In this example Item name and Quantity data has been insert into text box field but for enter Item Unit data we have use dynamic select box.

http://csharp-video-tutorials.blogspot.com/2015/04/jquery-add-event-handler-to-dynamically.html
In this video we will discuss, how to add event handlers to dynamically created elements. Let us understand this with an example.
The following example, allows us to dynamically create new list item (li), attach a click event handler and add it to the unordered list (ul). This happens when you click "Add a New List Item" button. The problem with this approach is that we are binding a click event handler to every list item. This means if you have 500 list items, then there will be 500 event handlers in the memory and this may negatively affect the performance of your application.
&lt;html&gt;
&lt;head&gt;
&lt;title&gt;&lt;/title&gt;
&lt;script src="jquery-1.11.2.js"&gt;&lt;/script&gt;
&lt;script type="text/javascript"&gt;
$(document).ready(function () {
$('li').on('click', function () {
$(this).fadeOut(500);
});
$('#btnAdd').on('click', function () {
var newListItem = $('&lt;li&gt;New List Item&lt;/li&gt;').on('click', function () {
$(this).fadeOut(500);
});
$('ul').append(newListItem);
});
});
&lt;/script&gt;
&lt;/head&gt;
&lt;body style="font-family:Arial"&gt;
&lt;input id="btnAdd" type="button" value="Add a New List Item" /&gt;
&lt;ul&gt;
&lt;li&gt;List Item&lt;/li&gt;
&lt;li&gt;List Item&lt;/li&gt;
&lt;/ul&gt;
&lt;/body&gt;
&lt;/html&gt;
A better way of doing the same from a performance standpoint is shown below. In this example, the click event handler is attached to the listitem (li) parent element (ul). Even if you have 500 list items, there is only one click event handler in memory.
So how does this work
1. When you click on a list item (li), the event gets bubbled up to its parent (ul) as the list item (li) does not have an event handler
2. The bubbled event is handled by the the parent (ul) element, as it has a click event handler.
3. When a new list item is added dynamicaly, you don't have to add the click event handler to it. Since the newly created list item (li) is added to the same parent element (ul), the click event of this list item also gets bubbled upto the same parent and will be handled by it.
&lt;html&gt;
&lt;head&gt;
&lt;title&gt;&lt;/title&gt;
&lt;script src="jquery-1.11.2.js"&gt;&lt;/script&gt;
&lt;script type="text/javascript"&gt;
$(document).ready(function () {
$('ul').on('click', 'li', function () {
$(this).fadeOut(500);
});
$('#btnAdd').on('click', function () {
$('ul').append('&lt;li&gt;New List Item&lt;/li&gt;');
});
});
&lt;/script&gt;
&lt;/head&gt;
&lt;body style="font-family:Arial"&gt;
&lt;input id="btnAdd" type="button" value="Add a New List Item" /&gt;
&lt;ul&gt;
&lt;li&gt;List Item&lt;/li&gt;
&lt;li&gt;List Item&lt;/li&gt;
&lt;/ul&gt;
&lt;/body&gt;
&lt;/html&gt;

http://csharp-video-tutorials.blogspot.com/2015/03/select-values-of-checkbox-group-with.html
In this video we will discuss, how to select values of checked checkboxes that are in different groups using jQuery. Along the way, we will also discuss how to pass a variable to jquery selector.
If you have just one group of checkboxes on your page, to get all the checked checkboxes you can use $('input[type="checkbox"]:checked').
However, if you have more than one checkbox group, then $('input[type="checkbox"]:checked') is going to select all checked checkboxes from both the checkbox groups.
If you prefer to get checked checkboxes from a specific checkbox group, depending on which button you have clicked, you can use $('input[name="skills"]:checked') or $('input[name="cities"]:checked'). This will ensure that the checked checkboxes from only the skills or cities checkbox group are selected.
Replace &lt; with LESSTHAN symbol and &gt; with GREATERTHAN symbol.
At the moment to get the checked checkboxes values, we are using a button click event. You can also use the click event of the checkbox to do this.
&lt;html&gt;
&lt;head&gt;
&lt;title&gt;&lt;/title&gt;
&lt;script src="jquery-1.11.2.js"&gt;&lt;/script&gt;
&lt;script type="text/javascript"&gt;
$(document).ready(function () {
$('input[name="skills"]').click(function () {
getSelectedCheckBoxes('skills');
});
$('input[name="cities"]').click(function () {
getSelectedCheckBoxes('cities');
});
var getSelectedCheckBoxes = function (groupName) {
var result = $('input[name="' + groupName + '"]:checked');
if (result.length &gt; 0) {
var resultString = result.length + " checkboxe(s) checked&lt;br/&gt;";
result.each(function () {
resultString += $(this).val() + "&lt;br/&gt;";
});
$('#div' + groupName).html(resultString);
}
else {
$('#div' + groupName).html("No checkbox checked");
}
};
});
&lt;/script&gt;
&lt;/head&gt;
&lt;body style="font-family:Arial"&gt;
Skills :
&lt;input type="checkbox" name="skills" value="JavaScript" /&gt;JavaScript
&lt;input type="checkbox" name="skills" value="jQuery" /&gt;jQuery
&lt;input type="checkbox" name="skills" value="C#" /&gt;C#
&lt;input type="checkbox" name="skills" value="VB" /&gt;VB
&lt;br /&gt;&lt;br /&gt;
Preferred Cities :
&lt;input type="checkbox" name="cities" value="New York" /&gt;New York
&lt;input type="checkbox" name="cities" value="New Delhi" /&gt;New Delhi
&lt;input type="checkbox" name="cities" value="London" /&gt;London
